along thd rail forming a portion of the track and remdve surface irregularities therein.

One oft the objects of niy invention 18 to provide an adjustment of the grinding member perm' ting (.f its being} readily and con veniently adapted to remove diflerentiliinds of surface\ irregularities or unevennesses in difi'erent liinds of rails. g

A further and special object-is to prov de an adjustment permitting of the removal of sharp depressions-in the rail, as at so-calleci pounded f'oints, by forming a long shallaw' depression merging into the straight portions of: the rail surface A furtherobj'ectis to better control the movement of the grinding member along the track while the grinding operation is taking place, butby a simple adjustment permit the vehicle can-lying the grinding member to be attached to ia hand-car or other drai't means and moved along the track at greater speed i with the grinding member out of operation.

In the specific formoi rnv invention here illustrated, I mountthe 3 riding members, W'nichare preferably emery-wheels, upon it truck having a main frame l0 formed of channel iron. centopposite ends. of the frame are be for the axles vHand 12, and upon tilt-354:: axies are pairs of Wheels 13 and 14. mounted to travel along the rforming the track Estending ss frameintermediate the. ends thereof i ero s rail 15 se i as a support for g rnding memuors. This cross-rail is i trated as being rigidly secured in la-a a point somewhatiiearer the axle 11 the. the axle 12, but it evident that the cros rail might be secured in place at L along the l ngth of frame of and mig so na-ziimted. as to 4 adjustment from one p Mounted upon ti two saddies or siides 1? be retained in engzw rail, but thereol in a track.

Mounted upon each saddle or horizontally movable slide 16 is a bracket or vertieally movabie slide 21. These brackets may be retained in engagement with the saddl any suitable manner, but prefe lily means of a dove-tailed guide and gentle-Wa as shown in the upper portion of Fig, Vertically disposed Within each hr ascrew rod having a handle 2-3 at per end and having with the projection fa l on the s by turning the handle 28 the i3; raised or lowered.

emery wheel. This emery wheel is of any shape or contour desired, dependent upon the shape andcharacter of the rail to be ground and the nature "of the irregularities to be removed. At the left-hand side of Fi 3 I have shown, one form of ywheel for grinding one type of rail and at the right-hand side I have shown a somewhat different wheel for grinding an o dinary Trail. Each bracket 21 carries a motor 27, here shown as anelectric motor, which preferably is detachably and adjustably connected to the bracket by suitable fastening means, such as the bolts 27 engaging the bracket through elongated slots From said motor power is transmitted to the shaft 25 in any suitable manner, as for instance, b a belt 28. By the; mechanism above desdi'ibed the emery wheels may be adjusted vertically or laterallj to any desired position relatively to theirails to be ground and when in this position'the truck or vehicle bearing the grinding members may be moved in engagement with the rails so as to grind the latter in a desired manner.

" For propelling the vehicle, 1* preferably provide one of the axles, for instance, the

' axle 11,; with one or more worm ,wheels 29 adapted to mesh with a worm 30 mounted on a shaft 31 extendirig upwardly to a point above the platform supported by the main frame. Said shaft preferably extends through a sleeve 32 which is pivotally mountedat'32 beneath the platform. With the shaft extending in the position indicated in Fig. 2 the worm is in engagement with the worm wheel and the vehlcle may be slowly advanced by turning the handle 31 at the upper end of the shaft. When it is des red to advance the vehicle at a greater ra of speed with the grinding member out of bperation the shaft 31 may be swung about the pivot 32 so that its axis will occupy the position diagrammatically indicated and the worm will be out of mesh with the worm wheel. Any suitable locking devic e may be employed for holding the shaft in either of its limiting-positions. The platform is preferably provided with a slot through which the shaft may move, and

pivoted dogs 33 are mounted, at the ends of the slots and movable into position within the slot to prevent the swingin movement of tlie shaft. In certain forms 0 my improved device I may mount an electric motor 50 on the platform and drive the car at the desired slow rate of speed by this motor Q0, releasabl to the supporting wheels 13in 'a-nysuit ble manner as by gearing 51, 52

and clutch 53, so as drive the Worm shaft 31.

In order [0 grind out sharp depressions or so-called pounded joints I preferably so mount the wheels at one end of the main frame that their axle may be brought to an eccentric position. By having the axle cccentric, the frame and therefor theisupported emery wheels may be caused to gradu- Y ally lower and raise during the advancement of the grinder through a predetermineddistance dependent upon the circumference of the eccentric wheels. As shown in F igs. -.2,

4 and 5, the wheels- 14 are bored to a considerably larger diameter than the axles, and within the bored out hub is placed a bushing 34. This bushing constitutes a mounting for the wheel upon the axle and has the passage therethrough disposed somewhat ofi' center. -The bored passage through the wheel is also oif center preferably the same amount as is the passage through the bushing 34 off center so that in rotating the bushing in respect to the wheel the axle'may be brought to the true center of the wheel or is shown .provided for fixing said wheel to said bushing in various positions of relative rotation to adjust the degree of eccentricity, between said Wheel and its axis, As shown, each bushing has a flange 35 disposed adjacent one surface of the wheel and provided with a plurality of notches 36 about the periphery thereof. I A slide, 37, having a key projection 37 for engagement with the flange 35 within its said notches, is adjustably connected to the wheel by screws 38 so that when it is moved into engagement with the flange 35 it will lock the wheel and bushing against relative rotation. Access to these adjusting means from the platform of the car may be conveniently had through an opening 39 in said platform which is normally closed by a swinging door 40.

Normallythe axle 12 is at the center of the wheel 14 so that the wheels and grinding members move substantially parallel and the emery wheels grind the track smooth and straight. When it is desired to grind out a depression. in the track, however, the wheels l4'are brou ht to an eccentric position, the eccentriclty depending upon the depth to rwhich-it is desired'togrind the rails at the joint. In Figs. 6, 7 and 8, I have shown the parts somewhatdiagrammatically and adjusted for grinding out a depression, the depressionand ,eccentricity adjustmentwbeing shown exaggerated to render the disclosure more clear. Starting with the parts in the position shown in Fig. 6 and slowly advancing the.

grinder, the emery wheel 26 will gradually lower as the grinder advances until-the lowest point of the main depression is reached, as shown in Fig. 7, and thenjwill gradually rise, grinding to less and less rial No. titj lilith tiled Jan. it), 1911 for rail grinder.
